Created: March 24, 2026The reviewer provides a detailed review of the Magene TEO Spider-based power meter, which is described as the flagship model featuring carbon crank arms. They discuss the installation process on their TLO Arrow bike, which required swapping to a 29mm spindle and a new bottom bracket, and compare its data output to their indoor smart trainer. The reviewer highlights the weight savings, accuracy, and improved installation process compared to the older aluminum model, while noting a minor complaint about the bolt size.
AI-Summary
Pros
- Uses carbon crank arms, which are a significant upgrade from standard aluminum
- Significantly lighter than the $300 aluminum version
- Very accurate with ±1% accuracy
- Data validation showed excellent agreement with smart trainer data (average power and cadence were nearly identical)
- Easy compatibility with Shimano chain rings
- Long battery life (330 hours)
- Offers a variety of crank arm lengths
- The power meter mechanism is identical to the older PES515, allowing for potential crank arm upgrades only
Cons
- Higher price ($549 USD) due to carbon arms
- Requires a 29mm spindle (DUB standard), necessitating a bottom bracket swap for users coming from standard 24mm Shimano setups
- The reviewer had to use spacers on both sides to eliminate play and achieve symmetry
- The 10mm bolt for final torque requires a specific tool not commonly owned; the reviewer suggests Magene should use an 8mm bolt instead
- The bearings for the required DUB bottom bracket are smaller and may have reduced longevity (though the reviewer reports 3,000-4,000 miles on similar units)
